A lawyer for the school suggested it would sue to overturn the ruling and seek a restraining order to halt the coming closure because its lottery in which parents compete to enroll their kids is coming April 1.

But revocation of The Ark's charter, or license, was approved, meaning that parents will soon get a letter advising them of their options for next year.

The Ark will finish out this school year, but the approximately 220 K-6 students there will start the 2014-15 year in other schools, mostly likely in the Troy district.

Many would probably go to Troy's School 2, which is in the same low-income North Central neighborhood.

That school also has been cited for poor test scores, but it has received a federal grant to help with turnaround efforts.

Troy officials have previously said they could accommodate The Ark's students.

The closure comes less than a month after The Ark got a brief reprieve when trustees held off on a decision. At the time, school supporters noted that the decision comes as the state is rolling out a new set of controversial tests based on the new Common Core learning standards. The Ark's lawyer, Kevin Quinn, noted that lawmakers are looking at possible moratoriums on using those tests for high-stakes decisions.

But evaluators also had measured other charter schools based on the Common Core tests and found The Ark wanting.

Joe Belluck, chair of the trustees charter committee, noted this marked the first revocation, or non-renewal, of a charter school by the body in two years.

Trustee John Murad cast a dissenting vote, citing the high level of parental involvement in the school and the challenge of placing students in other locations.

"You have these 200 students that will have to be broken up,'' Murad said.

Ark officials earlier said there is a 90-student waiting list to get into the school.
